Obama expands lead over Romney in two Wisconsin polls

President Barack Obama has opened up a bigger lead over Mitt Romney in Wisconsin since the party conventions, according to two new statewide polls.

The surveys diverge over the size of that lead.

Obama leads Romney by six points (51% to 45%) in a poll of 1,485 likely voters taken Sept. 11-17 by Quinnipiac University, the New York Times and CBS.

And the President leads Romney by a significantly larger margin — 54% to 40% — in a poll of 601 likely voters taken Sept. 13-16 by Marquette Law School. (That’s Obama’s biggest lead in Marquette’s polling since February).
